IMPROVED MEAT-UHOPPER.

digs 5:11am: marsh in in flgese itetters 23mm zmt making part at flge same.

Be it known that I, JOHN GEORGE HIRZEL, of the city of- Wilmington, in the State of Delaware,'have invented a. new and useful machine forchopping meat, which I term a. Rotary Meat-Chopper; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings making a. part of this specification, in which- Figure 1 is a. perspective view of the front of the machine.

Figure 2, is a. perspectiveview of the back, or rear view of the machine.

The driving-mechanism of my chopper is similar to that of other machines, and consists of the axles a and b, with their reciprocating wheels 0 and d, and the balance-wheel e, geared to or set upon an upright frame, f. To the upper or crank-axle b I attach a. hinged piston-rod g, which drives the intermittent rotary block it, which holds the knives s 8 attached to a cross-head, z, which traverses the guiding-ways Below this rotaryknifeblock is stationed the meat-block k, which is provided with a toothed rotating metallic rim, l, to which is fixed an inclined armor wing, m, reaching from the circumference to the centre of the bloclc for moving the meat. This rim is kept in place by means of the lugs 11 v, -The intermittent rotary knife-block h, and the rotating metallic rim Z, are moved by thepawls n and o, the pawl n being moved by the guide p, attached to the cross-head z, the pawl o, by the toothed rim of the knife-block h, in ascending.

'When the machine is put in motion, the pawl o operates upon the rotary knife-block it, moving it slightly or to the extent of aratchet-tooth; and the pawl 12,, in the same way, drives the rotating rim, Z, and is so arranged that the knives do not strike until after the rim 1, with its arm or wing m, has moved the meat slightly, thus presentinga new or fresh surface to the blades or knives while they are rotating.

I do not claim the knife-blades or any portion of the machine in itself orseparately; but

What I claim as my invention, and desire to secure by'Letters Patent, is The combination of any convenient number of knives or blades with the intermittent rotary knife-block h, the block k,-its toothed rotating metallic rim 1, and arm or wing m, and the pawls n and o, and guide, all arranged and operating substantially as described.
